Definitions

  • This invention is related to the field of remote sensing devices and systems for agricultural and other applications that are able to sense environmental conditions over large geographical areas and transmit such data to a base station to enable better resource management decisions.
  • This invention generally concerns remote sensing devices.
  • Remote sensing devices are well known in the area of agricultural production and environmental monitoring. Such devices sense soil moisture content, rain-fall in a particular area, sunlight irradiation over time, pollution and particulate loads in the atmosphere. These devices range in complexity from satellite coverage systems down to single soil pH monitors. Conventional, complex, remote sensing devices are very expensive and their data must be processed into a usable format. Such data is often out of reach to a small farmer. At their most simple, remote sensing devices do not provide sufficient amounts and types of data for a comprehensive overview of the environmental condition of an agricultural field which may vary from one part of the field to another.
  • a remote sensing device and system that is able to provide relevant environmental data to a farmer in order to optimize agricultural production.
  • a modern farmer requires detailed data on environmental conditions affecting plant growth and health over the agricultural area throughout the growing season.
  • Growing regions may cover a large geographical area such as a prairie state or province or they may be localized to counties and individual farms. This area can have different environmental characteristics so the growing conditions across the area may also vary.
  • a remote sensing device and system that provides environmental data specific to a growing region or a portion of a growing region.
  • the sensing devices need to be able to communicate with adjacent devices and with a data-reporting base station in a networked fashion to eliminate the need for an expensive uplink from each device.
  • the sensing devices and systems must also be compact, low cost, fully integrated, self-powered, able to co-exist within conventional farming practice, and maintenance-free so that they can be installed in remote locations over a large agricultural region.
  • my invention provides a remote sensing device that is compact, solar-powered, battery-free, fully integrated and and driven by a microprocessor using a plurality of software modules containing neural network elements.
  • My invention operates as a single autonomous device in a local area or as a system comprising a networked array of devices over a larger geographical area such as a farm.
  • the invention is able to acquire, process and transmit data by Radio Frequency (RF) to the operator directly, or via an Ethernet connection, a cellular telephone network, or a combination thereof, to the Internet.
  • RF Radio Frequency

  • the invention uses software comprising a plurality of modules and neural network elements to store, process and compute, manage, and transmit data.

  • Ease of association and security of data is achieved by a unique process, whereby a new 'adoptable' powered-up device is automatically associated with a unique base station identifier by passing it very near the base station;
  • An extraordinarily strong radio signal is received by the base device indicating the adjacent data acquisition device is to be added to the network so then the base station stores its unique family data on the device, irrevocably adopting the device and rendering it incapable of joining the network of any other base station with a different identifier;

  • the device is small, light-weight and robust enough that it can be mounted to a flexible pole, brushed aside by a contacting machine and then spring back in an operating position when the machine passes over it.
  • Power is provided by a power module comprising a set of small solar panels incorporated into the device. These solar panels are oppositely disposed and in an angular orientation to capture solar energy early and late in the day. The solar panels act redundantly to handle cloudy conditions and different orientations of the sun as it moves across the sky during the day. Energy from the solar panels is managed in an optimal way by the control module comprising software elements to charge super capacitors which store the energy in order to supplement the solar panels during energy demand periods that exceed solar panel output. This feature provides for prolonged operational periods of data acquisition and transmission when there is little or no sunlight available for power generation.
  • the power control functions of the invention allow for much lower power requirements and enable practicable battery-free operation. This gives the device a long life cycle and nearly eliminates the need for human maintenance oversight.
  • Multiple devices can be deployed in a network arrangement. When deployed in a networked configuration, one of the devices is programmed to be the base station and the remaining devices in the network act as data acquisition devices. Each data acquisition device is able to relay a message from neighbouring devices to the base station in situations where a given device is disabled, unable to reach the base directly by line-of-sight or if the base station is beyond the device's RF transmission range. Each device is able to store its data internally on a memory device and sends a copy of each piece of data it has stored to the base station. In this way should the base station be destroyed or stolen collected data can be recovered from the data acquisition devices. The base station receives and stores data from the data acquisition devices and then re-transmits this data by transmission means such as RF, Ethernet, Internet or cellular network to a data recipient at a home station.
  • transmission means such as RF, Ethernet, Internet or cellular network
  • the base station is the administrative control centre for the network.
  • the base station assigns digital identifiers to the other data acquisition devices so that the latter devices are linked irrevocably with the base station network.
  • the network will have a common ID root (the digital identification of the base station) and the data acquisition devices have this root name as an element of the device name. For example, if the base station is called ABC then that will be the root name of the network.
  • Associated data acquisition devices called XYZ and MNO will be adopted by the base station ABC and renamed ABC-XYZ and ABC-MNO. Other deployed data acquisition devices will be named in a similar manner.
  • the base station monitors network operations over each 24 hour period and manages a unique sleep/wake cycle for the data acquisition devices to conserve power during the dusk to dawn or any low-light intensity period.
  • the base station operates to ensure that efficient communications are maintained between the data acquisition devices and the base station as well as between the data acquisition devices themselves.
  • the base station will periodically open channels to each of the data acquisition devices in order to receive the data that has been acquired.
  • the data is then transmitted to the base station for storage, processing and re-transmission to a recipient. Processing may include reformatting the data received from the data acquisition stations into a format optimized for the receiving environment of the home station.
  • the base station also has a maintenance function. For example, if any specific data acquisition device reports an energy storage level that falls below a set voltage level, the base station will invoke a sleep/wake cycle, commanding the energy deficient device to de-activate for a period of time in order to conserve power in the energy storage capacitors. If the base station detects that the voltage drop is consistent across a plurality of data acquisition devices it will command the entire network to de-activate for a period of time ranging from 30 minutes to 2 hours. De-activated devices continue to wake momentarily at a time designated by the base station to communicate data in a burst transmission and then resume sleeping until sufficient energy is absorbed through their solar panels to resume a fully-awake state.
  • the base station will receive data from the data acquisition device at 30 minute intervals as long as voltage levels are stable. If voltage levels rise then the data acquisition device will resume normal full-time operation. If voltage levels continue to fall the base station will command the data acquisition device to sleep for longer periods to preserve power. This allows data capture during dark periods when energy is at its lowest as well as efficient operation during daylight regardless of weather conditions.
  • the operating range between adjacent data acquisition devices and the base station is up to 1500 feet.
  • the power conservation features of the invention are critical to continuing data collection and transmission during seasons where darkness and low light conditions may last for up to 16 hours in a day.
  • One more feature of the invention is that the data acquisition devices deployed in a network configuration can be readily re-deployed, moved and replaced anywhere within the operating range of the network.
  • the internal communications module operating in each of the devices is able to re-establish communications with the base station and with neighbouring devices without human intervention.
  • Another feature of the invention is the use of a sub-group selection procedure that is managed by a neural network in the communication module within the base station.
  • the communication module neural network is trained by a first algorithm for achieving power optimized data transmission.
  • This feature optimizes RF communication between the networked devices, minimizes communications failures and reduces power consumption. This permits use of small-sized solar panels, thus reduces the size and increases the cost effectiveness and utility of the devices.
  • a further feature of the neural network algorithm in the communications module is the identification and correction of communications faults. If the base station identifies communication faults due to an over population of data acquisition devices communicating over an assigned RF frequency the base station will invoke the sub-group selection procedure which automatically assigns groups or tiers of data acquisition devices to multiple sub-bandwidths around its 915 MHz centre frequency to prevent cross-talk between devices and between adjacent networks. This optimizes communication and reduces transmission failures, reducing energy demands.
  • communication protocols managed by the communications module in each data acquisition device and the base station ensure that each data acquisition device is aware of and is regularly updated on the presence of any newly established communication links via other data acquisition devices to the base station.
  • the design provides for a highly efficient use of solar energy, very low power use during operation, power storage by super capacitors, and the use of intelligent neural network control module technology to enhance RF communications by optimization of sub group selection managed by the control module.
  • a further feature of the invention is that the device facilitates data collection, data file storage and management, and transmission of diverse data types without human intervention.
  • the data acquisition devices are able to autonomously establish alternative communication pathways to and through other near-by devices that are in communication with the base station. This ensures efficient operation of communications within the network and compensates for new obstructions, failed devices within a communication pathway, and removal or destruction of devices. It also enables ready deployment of additional devices.
  • the device is about the size of a 60 watt light bulb and can be installed on an appendage such as a flexible pole support for above-ground mounting. This permits installation in a farm field where the pole-mounted device may be in contact with a farm machine, automated irrigation machinery, or a farm animal. It is housed in a rounded plastic weather-proof case and is thus resistant to moisture, dirt and contact with other objects. If installed in a field with moving agricultural machinery, the device can be attached to the flexing pole and be placed above the ultimate crop height to ensure communication connectivity. When brushed aside by a passing pivot irrigator, it will spring back into place and resume connectivity.
  • the invention can be connected to or incorporate a number of sensors and components such as a light sensor, temperature sensor, a web camera, GPS transceiver, soil moisture sensor, soil pH sensor, irrigation water flow meter and a barometric pressure sensor.
  • sensors and components such as a light sensor, temperature sensor, a web camera, GPS transceiver, soil moisture sensor, soil pH sensor, irrigation water flow meter and a barometric pressure sensor.
  • each device of the invention may have an accelerometer, GPS, diagnostic LEDs and audio-generating devices in a user interface.
  • a remote user may also be able to interface with any of the data acquisition devices through cloud-based software that communicates with the base station, and from there relay commands and new programming to the data acquisition devices.
  • a camera is installed on the device it can be physically redirected over a limited range to monitor leaf growth, fruit growth and visual appearance of the crop.
  • the device could be mounted on a gimbal and hand oriented to monitor a specific object.
  • the camera can also be used for infrared sensing and area security, enabling monitoring by a remote user.

  • the base station will periodically poll each data acquisition device 10a to 10f individually by an RF signal 9 and the queried device will transmit a copy of its data to the base station for storage and processing. A copy of the data always remains on the memory storage device for redundancy. While RF communications appears to be a simple means of implementing the network communications, other means can be used to communicate between devices and the base station such as a cellular network or a wired network.
  • the base station 11 is connectedto the Internet 13 by an Ethernet or modem device 230.
  • Power is provided to the individual device 10 and the base station 11 by the dual solar panels 90 and 92 shown in Figure 3B. Solar energy reaching the solar panels can be enhanced by magnifying windows 30 and 32. Power is managed by the power module programmed on the electronic control boardmicroprocessor 122.

  • the output of the solar panels is optimized along with the charge rate of the super-capacitors by the power module.
  • the super-capacitors also provide pulsed energy bursts to operate equipment at times when energy requirements exceed the output of the solar panel, such as during low light conditions.

  • data acquisition devices deployed in the illustrated network configuration may not be able to communicate directly with another data acquisition device or with the base station by line of sight due to intervening obstructions such as hill top 102.
  • communication is facilitated by individual devices having the capability to recognize neighbouring units and utilize those units to relay data to the base station where it is stored and transmitted.
  • the stored data now also contains a record of the new pathway.
  • the network of data acquisition devices is configured by the unique communication sub-module programmed into the control module of each device and in the base station unit to optimize communication between devices and provide for regular checks of connectivity.
  • the base station assigns and records an identifier to each data acquisition device. This allows an operator to relate the data received from a given data acquisition device to its location, specific crop or application.
  • Each of the data acquisition devices is regularly polled at 15 minute intervals by adjacent data acquisition devices in the network so that it may keep track of its communication with adjacent units and the communication pathway by which data is relayed either directly to the base station or by means of an adjacent device to the base station. Thus if a unit is disabled, alternate communication pathways are always available to each device. Data acquisition device relationships are kept updated so that an alternate path can be created to report data.
  • the ability of the data acquisition devices to establish fresh communication pathways to relay data back to the base station facilitates deployment of the invention over large areas that include natural and human made obstacles.
  • the adjacent data acquisition devices can create data pathways that circumvent the damaged device.
  • the base station charts all data pathways and uses a neural network pathway analysis routine within the communications module to learn and relearn which of the charted pathways are the most efficient, based on the pathway's ability to convey uncorrupted data.
  • the neural net elements of the communications module in the base station enable a 'frequency sub-banding' capability. This intelligently assigns varying frequency sub-bands to neural-net selected groups devices within a networked configuration depending on their current routing pathways.
  • the neural net element within the communications module enables concurrent communications within a large network of these devices thereby reducing communication times and power demands. This further enables the small size and cost effectiveness of the devices.
  • the base station groups devices into sub-network groups along optimal pathways and assigns those groups of devices a sub-frequency band around the system's 915MHz centre frequency range [915MHz Sub-Band 1 to 4]. Transmitting concurrently on different frequencies eliminates data corruption and thus fewerre-transmissions are needed along each pathway, allowing the base station to rapidly switch between each sub-network's frequency and collect its messages. This results in significant power savings.
  • each data acquisition device Prior to installation of the network each data acquisition device is passed so near the operating base station that the base station detects the strongest possible radio signal emitted by the data acquisition device. Once the signal is detected, the base station uses this signal to initiate an identification sequence. It reads and records the unique identifier of the data acquisition device and then transfers its own unique base station identifier to it. The result is a combined base station/data acquisition device identifier which is irrevocably stored in the data acquisition device's memory.This irrevocably 'adopts' each data acquisition device to the base station and identifies the entire network of data acquisition devices as controlled by the base station. This is a security feature that prevents a data acquisition device of one network from sharing data with an adjacent network or a base station from communicating with data acquisition devices not a member of its network family. Thus the data is secure and communication is confined to exchanges between devices within the network.
  • the base station 11 administrates the operation of the network 100 and records the identifiers of each of the individual data acquisition devices. For example, if the base station has a digital identifier as '11' and the data acquisition stations have respective identifiers '10a' to '10e' then the adoption process will identify each data acquisition device controlled by base station 11 as '11/10a' to '11/10e' and the network will be known as network '11'.
  • the adoption process codifies the relational position of each data acquisition device within the network; coordinates how individual data acquisition devices join the network and communicate with the base station and with each other; handle routing of data received from each data acquisition device in the network; and, communicate externally with the Internet 13.
  • an installation start-up sequence might appear as shown in Figure 13:
  • Step 300 map network onto desired plot of land.
  • Step 302 - identify the number of data acquisition devices required for the plot of land and assign one of the devices as a base station.
  • Step 304 turn on all devices and pass each data acquisition device near the base station whereupon the base station detects a RF signal which will identify the data acquisition device as an 'adopted' device into the base station's network.
  • Step 306 - provide an identifying digital name to each data acquisition device in the network 11/10a to 11/10f.
  • Step 308 - deploy the base station and the data acquisition devices onto the plot of land.
  • Step 310 - base station checks communication links between it and all data acquisition devices in the network.
  • Step 316- if the communications links are good then the base station can receive data from the data acquisition devices.
  • Step 318 - base station collects, stores and processes data.
  • Step 320 - base station transmits data to Internet.
  • Step 312- if connectivity is not good then the base station will check connectivity between adjacent data acquisition devices;
  • Step 314- data acquisition devices will establish a relay between adjacent data acquisition devices to communicate with base station;
  • Step 316- data is transmitted to the base station
  • Step 320 -data is transmitted to the Internet.
  • an additional characteristic of the invention when deployed in a network array is a 'sleep/wake' cycle.
  • This cycle is intelligently managed by the base station.
  • the cycle facilitates the conservation of energy and allows the network to continue collecting and transmitting data during prolonged dark or low light conditions when there is no or little current generated by the photo-voltaic cells.
  • a single data acquisition device will only use a tiny portion of its stored energy for a transmission.
  • the base station commands the device to cease function and 'sleep' for a period of 30 minutes.
  • the acquisition device Once the acquisition device 'wakes' it will transmit a pulse of data to the base station and if energy is still below the waking daytime voltage will resume sleeping until the next assigned wake time. If other devices in the networkcontinue to fall in voltage, all devices in the network are commanded by the base station to 'sleep' for an assigned sleep period.
  • the assigned sleep period can lengthen to a maximum of 2 hours depending on the energy depletion in the network.
  • the base station monitors the data acquisition devices and manages their sleep cycle and its duration to optimize power consumption while still facilitating regular data gathering by all the units in the array during non-light periods.
  • the power management features of the invention allows the network to continue data gathering, transmission and storage for prolonged periods of low light or darkness. Fully charged devices are capable of conducting the sleep/wake cycle for up to 36 hours.
  • the sleep/wake cycle is shown as comprising the following steps:
  • Step 500 - a data acquisition device transmits a low waking day voltage signal to base station 11.
  • Step 502 - base station 11 initiates a sleep/wake cycle.
  • Step 504 - base station 11 transmits a sleep signal to device 10 to sleep for 30 minutes.
  • Step 508 - if the system voltage of device 10 is equal to or greater than the waking daytime voltage then the device 10 continues fully awake operation.
  • Step 510 - if the system voltage of device 10 is not at the waking daytime voltage, and if its voltage has further decreased the base station 11 will send a signal to the device 10 to sleep for at least 30 minutes so that the device charges.
  • the device can be installed on a flexing pole to allow the unimpeded passage of farm machinery.
  • the invention is equally suited for any setting where environmental data is recorded for scientific and biological research, safety and security applications, monitoring of hazardous sites and industrial applications such as plants, pipelines and electrical grids, factories and processing operations. With sunlight or artificial forms of illumination, the invention can also be deployed to monitor environmental conditions and environmental quality in buildings such as greenhouses, animal barns, hatcheries and fish farming operations or in any situation where the health of humans and animals requires monitoring and control. Finally, the invention can be deployed in remote locations for scientific, weather data, or other data collection purposes where there it is difficult to send a person to collect the same data. Remote deployment may include hydroelectric engineering sites, water gauging networks, tsunami warning locations, unstable terrain and landslide situations, highway snow safety structures and isolated sections of pipelines and power grids. The data acquisition devices can be used to detect emergencies and maintenance requirements.
